    Addition of a multifunctional ionic additive in mixed two-dimensional–three-dimensional bromide/chloride perovskites enables efficient blue perovskite LEDs with external quantum efficiency of up to 21.4% and half-lifetime of 129 min at an initial luminance of 100 cd m–2.

    Superconducting electro-optic modulators for a cryogenic-to-room-temperature link are demonstrated. The record-low half-wave voltage of 42 mV is achieved on a 1-m-long modulator. By matching the velocity of microwave and optical signals, a 0.2-m-long modulator can achieve a 3 dB bandwidth of over 17 GHz.

    Researchers overcome the typical scintillator trade-off between high efficiency and speed. In organic scintillators, researchers drove hot excitons into fast singlet emission states without involving the lowest triplet states, which led to a fast radiative lifetime and strong light yield that may be applicable to ultrafast detection and imaging.

    Luminescence solar concentrators are improved by using a laminated structure that creates a practically non-decaying optical ‘guard rail’ for light. Design rules enabled external quantum efficiencies as high as 45% for 450 nm light, yielding a device efficiency of 7.6%, probably useful for energy-harvesting windows.

    Using a self-referenced attosecond photoelectron interferometry on helium atoms, the electron subcycle motion along the light propagation direction is observed in the 15 pm range. A time delay of 15 ± 10 as between the electric-dipole and electric-quadrupole transitions is also revealed.

    Dynamic resonance fluorescence spectra beyond the Mollow-triplet are observed in a In(Ga)As quantum dot in a micropillar. Multiple side peaks, excitation-induced spectral asymmetry, and cavity filtering effects are experimentally observed and theoretically reproduced by a full quantum model that includes phonon-induced decoherence.

    A skyrmion is a topologically stable field configuration. A non-local skyrmion, which has been hitherto elusive in condensed-matter physics, is realized by using entangled photons with a non-trivial topology. The connection between the notions of topology and entanglement is investigated, revealing topological invariance even when entanglement is fragile.

    Researchers propose a laser pulse compression method for exawatt to zettawatt lasers based on spatially varying dispersion of an inhomogeneous plasma. This may enable, for example, pulse compression of a laser pulse from 2.35 ps to 10.3 fs. The approach is robust at high intensities.

    We posit that inconsistent interpretations of experimental data have led to inaccurate claims on metalens focusing efficiencies. By performing a meta-analysis, we show that extraordinary claims of high focusing efficiency at high numerical apertures are, unfortunately, not yet backed by rigorous simulation or experimental results.

    Since the inception of the idea of temporal solitons in optical fibres, published in 1973, the concept of optical solitons has revolutionized the fundamental science of optics and photonics technologies. This Perspective gives an outlook on the future of solitons in ultrafast lasers, frequency combs, biomedical applications, telecommunications and signal processing, as well as the emerging new science of solitons.
